My invention relates to coke ovens or the like of the well-known chamber type defined laterally by heating walls and below by a base for supporting thecharge in which the volatile products of distillation developed in the charge in the chamber are withdrawn downwards through the base of the chamber.

According to the invention, exchangeable frames comprising bars arranged like a furnace. grate are inserted in vertical openings or passages provided in the base of the oven chamber, through whichthe volatile products of distillation can flow to a lower horizontal channel preferably extending along T the length of the chamber.

This arrangement ensures an efiicient withdrawal of the gases and vapors generated without the passages being blocked, and enables an undisturbed discharge of the finished coke. l

A further object of the invention is to provide parts serving the said purpose which can be readily removed and exchanged when worn by use.

A still further object is to prevent any 7 liquid condensates arising in the coal charge from finding their way into the passages and blocking them by the incrustations' formed. 7

An example of a construction according to the invention is shown in the accompanying drawings.

Fig. l is a vertical cross section of a horizontal coke oven showing one oven chamber the oven chamber (1, a base 8 exists upon which the coal charge rests and the finished coke slides parallel to *the heated side walls when being discharged.

' In the longitudinal centre line of the base '15::

s' of the oven chamber there is a series of vertical openings or passagesyc' through which all volatile products] of, distillation are led from the chamber intojajdraw-ofi channel 70 provided below the chamber. In

each of these passages 0. a frame a is inserted from above so as tobe'easily exchangeable.

It consists preferably'of a boxshaped mem -J 7 her which tapers downwards andis 'provided with. bars 1', arrangedlike a furnace grate, which bars run parallel to tl1e'lon'gitudinal axis ofthe chamber .and therefore also in the direction *ofthe 'cokedischarge and leave between them spaces forfthepassage of the gases and vapors The bars '0' arealsoa-tapered downwards, so;that the free spaces are somewhat-"wider below than above. The upper common surface ofthe frame and of the harslies. flush with the sur face of the base 8 of the chamber. The 7 frames comprising the bars. can be nade of metal, for example cast iron, or offag ceramic material, for example well-burnt fireflclayg.

The construction of; the. frames aprevents their being choked byparticles ofcoal or the like duringthe working oflthe oven; If 7 during the charging of the oven chamber,

particles of coal find their way into, the

spaces between the bars -r. and are ,wedged therein, they will eitherbe cut out during the discharge of the finished cokejor. forced downwards by the pressure due to the coke sliding over them when the latter is pushed out from the oven chamber. The arrangement of the bars 7 paralleltothe longitudinal axis ofthe; chamber: and to 1the;di-,

.rection of discharge ofthe finishedfcoke considerably, lessens the friction and the resistance to sliding duringthe discharging. Likewise, by arranging'the tops of. 1,-;the

frames a and bars 1' gflush with thesurface of the bases, anydisturbance or obstruction of thedischargingqis obviated. ...Should a frame a in the course'of; time bewornaway too much or perhaps, forexample, in conse' quence of ncrustations formed; allow too smalla free passage, itcanberemoved means of suitable tools'fromits. particular O i 6 nd r r w j yf ano 1 l r cleansed and again inserted. The frames at can'be removed at places adjacent to the ends of the oven chamber laterally through i the door openings, and in the middle portion of the vchamber'from above through the charging'openings inthe chamber ceiling.

The base 8 of the chamber is preferably, as shown in Fig. 1, somewhat raised in the centre and sloped away to each side, in order to prevent any liquid condensates which are formed from'the products of distillation flowing into the frames at and forming a.

choking incrustation. In a chamber base. constructed as shown, the condensates which eventually arise tend to'flow laterally to the hot oven walls and to be evaporated on the hot oven base, with the advantage that the latter is also cooled bythe consumption of latent heat of evaporation.
